| Note | Comment |
|---|---|
| Note 1 | Connect the wire to terminal 5 for a 1 Ampere CT. Connect the wire to terminal 5A for a 5 Ampere CT. Do not use 1 ampere CT with a VAR/PF Controller. |
| Note 2 | Connect the remote voltage adjust potentiometer between terminals 6A and 7. Remove the jumper between terminals 4 and 7. The remote voltage adjust potentiometer should be rated at 10 K Ohm and 2 Watt.
Place the jumper between terminals 6A and 8 for 1 V/Hz underfrequency slope. Remove the jumper between terminals 6A and 8 for 2 V/Hz underfrequency slope. Place the jumper between terminals 6A and 9 for three-phase sensing. Remove the jumper between terminals 6A and 9 for single-phase sensing. |
| Note 3 | Connect terminals 2 and 3 to the VAR/PF controller. Short terminals 2 and 3 when the VAR/PF controller is not used. |
| Note 4 | For three-phase voltage sensing, connect the wiring to the secondary winding. Phase rotation with transformer T1 is important.
Connect terminal 22 to the PT on T1. Connect terminal 24 to the PT on T2. Connect terminal 20 to the PT on T3. |
| Note 5 | Use twisted, shielded cables. |
| Note 6 | Single-phase, 220 VAC to 240 VAC secondary transformer winding, 50 / 60 Hz, 3125 VA |
| Note 7 | Three-phase, 63 VAC to 105 VAC, 50 / 60 Hz, 3125 VA |
| Note 8 | Connect jumper from terminal 28 to ground terminal on "Permanent Magnet" generators as per the following qualifications.
1) LS65-12 Revisions A through E 2) VR6 Revisions A through B 3) VR6 Revisions C and later have an internal jumper and do not require and external jumper. |
